mul()

diyfp detail::dtoa_impl::diyfp::mul ( const diyfp & x, const diyfp & y )

inlinestaticnoexcept

returns x * y

Note

The result is rounded. (Only the upper q bits are returned.)

normalize()

diyfp detail::dtoa_impl::diyfp::normalize ( diyfp x )

inlinestaticnoexcept

normalize x such that the significand is >= 2^(q-1)

Precondition

normalize_to()

diyfp detail::dtoa_impl::diyfp::normalize_to ( const diyfp & x, const int target_exponent )

inlinestaticnoexcept

normalize x such that the result has the exponent E

Precondition
